AUTOMATIC ADVERTISING DEVICE.

SPECIFICATION formingpart of Letters Patent No. 272,184, dated February 13, 1883.

' I Application filed November 30, 1881. Renewed January 12, 1883. (No model.)

To all whom it may concern:

Be it known that I, ALFRED ANDERSON, a subject of the Queen of Great Britain, residing at Paris, in the Republic of France, have in vented ce'rtain new a nd useful Improvements in Automatic Advertising Devices; and I do hereby declare the following to be a full, clear. and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention appertains to devices for the automatic display of advertisementsthat is to say, mechanical means for displaying and varying mechanically the display of advertisements of all kinds. In the annexed drawings 1 have shown my invention as applied to a counter-scale; but it may, in like manner and by a slight modification in the construction and combinatiOm-of its operating parts, be applied to post-oifice scales and all other kinds of scales which are mounted upon a suitable hollow box or casing adapted to contain the ,prism or cylinder upon which the advertise- L designates the scale-beam, which is mounted upon the top of box E, and has a bowl, F F, at each end. At one end of beam L is an arm or detent, K, which projects down through an aperture in the top of box E into the interior of the same, where it engages with a ratchet-wheel, I, that is secured coucentrically upon one end of a prism or cylinder, E, that is mounted lengthwise within the casing E between its apertures or windows G G. The other end of the scale-beam has a weight or counterpoise, l, to balance the pawlarm K.

The advertisements are displayed serially upon the circumference of the c \linder H, which is rotated intermittently by pawl K engaging with the ratchet-wheel I every time the beam is dipped or tilted. In this manner the advertisements are displayed successively through the apertures in the casing E, which should be placed in a conspicuous position, so as to attract the attention of the public.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States' In an advertising device, the combination of the casing E, having apertures G G, cylinder H, having ratchet-wheel I, and scale-beam or balance L, having the detent K and counter-Weight l, constructed and arranged to operate substantially in the manner and for the purpose herein shown and set forth.

In testimony whereof I have hereto affixed my signature in presence of two witnesses.

ALFRED ANDERSON.
